How We Chose These Top Picks

The right kind of dehumidifier can do wonders for your home or wherever you decide to use it, whereas the wrong one can be a wasteful investment and that’s not what we want. Therefore, we decided to combine the very best in each category and provide you with a review of them.

All of the below-mentioned dehumidifiers are some of the very best for various reasons. Let’s look at those reasons to help you make a decent choice.

Portable and Convenient

All of these are lightweight and easy to travel with. You can shift them from one room to the other with great ease as they are highly convenient to move. The small and portable design makes them easy to store and these won’t clash with the aesthetic of your room either.


The dehumidifier you invest in should not make a lot of noise while working, as it can be distracting and unpleasant. Ideally, it would quietly do its job such that you won’t even notice its existence except by the improved air quality.

Room Coverage

You need to know the exact size of the space where you plan on running the unit. A small dehumidifier works well in rooms, basements, RVs, boats, etc. The products we talk about all mention the cubic meters or square ft. of the area they work best.

Water Capacity

If you live in a highly humid place, you need a dehumidifier which can suck in more moisture. Small humidifiers usually have the capacity of 16 to 72 ounces, and after that, you will need to empty your unit.

Automatic Shut-Off Feature

This feature makes a product user-friendly. It shuts off the unit when the dehumidifier’s water capacity is full. Therefore, it can come in handy.

People love this compact dehumidifier for a lot of reasons. Recent buyers love the small size, with some mentioning they were surprised by just how small it is. Many people mentioned that it fits into crawl space and that it’s extremely effective at lowering the humidity level. Setup is also simple.

Why it Stands Out to Us

We also really like that this dehumidifier is so compact and easy to set up. In addition to the horizontal flow-through design and the small footprint, this dehumidifier is engineered to operate in low-temperatures and in spaces with poor airflow, which is why it’s perfect for a crawlspace.

How Does a Small Dehumidifier Work?

Small humidifiers work by drawing warm air into their coils through the fans. Warm air then travels through the refrigerated coils of the machine and contracts, pulling excess moisture from the air. The condensation is left inside the dehumidifier.

Dehumidifiers are connected to a storage tank, so as the condensation occurs, water collects in the tank or runs out through a continuous drainage system. Cool air is then released back into the hose through the other side of the machine.

Where to Place a Small Dehumidifier

Place a small dehumidifier in an area with no excess fresh air from outside and no water is coming in to ensure you control humidity efficiently. Ensure that you keep the intake and exhaust away from the wall, and do not place them near open water. Keep the dehumidifier away from hanging curtains or draperies, too. They could be pulled in by the intake.

Your electric dehumidifier will most likely use a ground fault circuit interrupter-protected circuit. You should also ensure the product has clean fans. Clean the fans with water and reinstall them when they have completely dried. Dirty fans reduce the efficiency of dehumidifier capacity.

Check the electrical requirements for your dehumidifier, too. Most require a 115 VAC power outlet. Follow the installation instructions included with the model you choose. Most require a flat surface to avoid leaking. 

Most dehumidifiers drain through gravity, so the water does not condensate upwards.  Condensate can be drained using a clear vinyl hose and threaded adapter. Also, it has to have a drain trap.

Best Places to Use a Small Dehumidifier

Use a small dehumidifier in any room of your home that has a moisture problem. Mold can grow anywhere, and every house is different, so the best place to use a small dehumidifier is where you need it most. 


A bathroom is an ideal place for dehumidification because long, hot showers and baths raise the humidity level quickly. This condensation builds up, leading to mold and mildew. If the extractor fan in your bathroom isn’t getting the job done, consider adding a small dehumidifier. Run a bathroom dehumidifier for about 20 minutes after every shower, and you should soon see a decrease in mildew and mold growth.  

Crawl Spaces

It is common for humidity to accumulate in crawl spaces in the winter, then the temperature inside is warmer than the temperature outside. A small dehumidifier tucked into a crawl space does the trick, but make sure it has a strong fan and specifically mentions that it’s for a small space.


Kitchens are a big source of humidity in the home since cooking, dishwashers, and refrigerators all add moisture to the air. Too much humidity not only increases the danger of mold growth but can also affect how long the food in your pantry and cupboards stays fresh. Placing a small dehumidifier in the kitchen when cooking is often a great way to help combat humidity.

Humid basements with a musty odor are pretty common. Because basements are underground, they’re cooler and more vulnerable to water getting in from the outside. If your laundry room is also in the basement, it can increase the humidity even more. Hooking up a dehumidifier in the basement is usually pretty simple as you can make use of the drainage system already in place for the laundry room. 

Why Would You Want a Small Humidifier?

If you live in a flat or need a dehumidifier for a smaller area, investing in a small dehumidifier is your best bet. Small dehumidifiers can be your best friends if you don’t have space or don’t have need of a big one. Living in humid areas means your place gets a lot of mold and mildew. It can also happen if you live near a water source.

Mold and mildew contribute to a moldy odor in your house, which is unpleasant. Furthermore, they may also stain the walls of your house.

If the humidity intensifies and is more than 40%, you will feel it on your skin and your hair may get all frizzy, thus it can be uncomfortable to live with. Moreover, your furniture suffers too, if the humidity is too high and the wood will decay faster than it’s supposed to. Thus, a small humidifier can do wonders to improve air quality.

What it basically does is suck in the musty air, filter it, and release it back into the environment with less moisture. The air would then have controlled levels of humidity in it.

People Also Ask

Below are some common questions related to small dehumidifiers:

How Many Watts Does a Small Dehumidifier Use?

A dehumidifier uses 580 watts. This makes it energy efficient, which is above the Energy Star standards. It draws 5.1 amps while operating with an efficiency of 5 pints of water per kilowatt-hour.

How Much Does a Small Dehumidifier Cost?

Small dehumidifiers span a wide range of prices. The cost can range from as low as $30 up to over a thousand dollars.

Is a Small Dehumidifier Worth it?

A small dehumidifier is highly efficient in removing water and relatively quiet. This makes it perfect for use in nearly every condition.

How Long Can I Leave My Small Dehumidifier Running?

A dehumidifier should not be left running for long, especially when there are children around.

How Often Do I Need to Empty a Small Dehumidifier?

A tube should be attached to the dehumidifier to remove the water.

Place the other end of the tube to a drain, plug-in power, and the machine does its work.

Why are Some Dehumidifiers Smaller Than Others?

Some humidifiers are smaller than others because they may be the desiccant type. Desiccant dehumidifiers are smaller in size than refrigerant humidifiers as they do not have a compressor. Desiccant dehumidifiers have numerous advantages to them like being able to work better in lower temperatures, however, they are less energy efficient and have lower water capacities.

It is important to know that dehumidifiers need space around them that allows a consistent flow of air for them to work efficiently and do their job well.

Do All Small Dehumidifiers Have Shut Off Functions?

The best dehumidifiers are those that have an automatic shutoff function. Small dehumidifiers have a feature that automatically shuts off the unit when the water capacity is full and prevents spillage. Mostly, machines will have an indicator that will tell you when it is time to empty the tray. Therefore, spillage really isn’t the biggest of concern here if you pay attention.
